Design Of Three-Valued Logic Gates Based on Knowm Memristors

Three-valued logic has significant advantages over traditional two-valued logic in terms of single-channel information-carrying capacity, enhanced data-transmission bandwidth of interconnected lines, and information density of integrated circuits. However, CMOS-based three-valued logic circuits consume large amounts of power and are not easy to integrate on a large scale, so they are less commonly used in practice. The emerging memristors are small in size, low in power consumption and compatible with CMOS process. In this paper, we design three-valued basic logic gates based on the SPICE model of Knowm memristors, which provides a new idea for the design of three-valued digital logic circuits.
